Skull: Massive, longitudinally and transversally convex, due to the relief of the chewing muscles and
muscles of the neck.

Muzzle: Of the same length as the skull. The line joining the orbiter apophyses should be equidistant
from occipital and upper maxillary aveoli.

Eyes: Dark in color, well separated, rimmed by black or pink eyelids. The look must be alive, intelligent
and hard.

Maxillary: Well adapted, strong, without prognatism. Large, well implanted teeth.

Nose: Strongly pigmented in black, with slight stop at the end. Ample nostrils.

Ears: Well on top of the head; erect or semi-erect of triangular shape. Must always be cropped.

Lips: Fitting closely, short, with free borders pigmented in black. (Short lips are a must, to
allow the dog to breath through the corners of its mouth when holding a prey.)

Occipital: Should not be outstanding, masked by powerful neck muscles. Head/neck insertion must be
arched.

Neck: Thick, arched and lithe, with heavy, abundant skin which wrinkles as on the old mastiffs (Sufficient
elasticity on neck skin is required to allow for displacement when held by prey and to protect its body flesh from injury
when bitten or clawed).

Chest: Ample, deep, giving the impression of big lungs. In front, the sternum must reach under the
elbows. Upper back or Withers: High. Very strong with great muscular relief.Thorax: Ample, on side view it should reach
under the elbows.Spine (back line): Higher on the upper back (withers) and smoothly sloping to the hind (on adult animals
having well developed back muscles and kidneys, the spine arches down slightly between upper back and hind –dip-; a
longitudinal “channel” along the spine is created by the relief of spinal muscles).

Tail: Long and thick, should not extend past the hocks and be naturally carried down. In combat (it) is always up,
in continuous lateral movement, as when a dog greets its master. It should never curl over.

Weight: 40 to 45 Kg (88 to 99 lbs.)

Height: 60 to 65 cms. (23.6 to 25.6 inches)

Coat: Completely white. Any marking or spot of any color must be disqualified as an atavism (white
dogs showing strong black pigmentation on the skin should be considered non-apt for breeding, as this physical trait may appear
and become predominant in offspring).

Disqualifications: Blue eyes; deafness; spots or markings on coat; long hair; pink or predominantly
pink nose; prognatism (overshot or undershot), pendulous lip, “hound” head, more than one spot on the face, any
body disproportion.

BRIEF HISTORICAL
SUMMARY : This breed has its origin in the province of Cordoba, in the central (Mediterranean) region of the Republic of Argentina.

Its creator
was Dr. Antonio Nores Martinez, a (renowned) doctor and member of a traditional local family. In 1928, his passion for dogs,
perhaps a family legacy, led him to set the bases and a standard for a new dog breed which he named : Dogo Argentino.
His work was based upon the methodical crossbreeding of several pure breeds with the « old fighting dog from Cordoba »,
a dog which was very strong and vigorous but lacked psychic and genetic stability. This local breed had been the product
of the crossbreeding among Mastiffs, Bulldogs and Bull Terriers and was widely known and appreciated by fervent dog-fight
fans, a very popular activity at the time which embraced all social classes.

After a
thorough and minute character study and selection, through different generations, Dr. Nores Martinez accomplished his purpose,
obtaining the first « family ». At the beginning it was generally considered a dog for fighting but Dr. Nores
Martinez’s liking for hunting led him to take the dog to one of his habitual hunting trips, where the new breed demonstrated
its skills, thus becoming a key figure in all his trips. Thus it became quickly an excellent « big-game hunting
dog ».

With the
passing of time, this adaptating capacity has made this dog very versatile as regards functions; it has proved to be a noble
companion and a loyal and insurmountable protector of those it loves. Its strength, tenacity, sharp sense of smell and
bravery make it the best dog among those used for hunting wild boars, peccaries, pumas and other country predators which can
be found in the vast and heterogeneous areas of the Argentinean territory. Its harmony, balance and its excellent athletic
muscles are ideal characteristics for enduring long trips in any weather conditions and then fighting fiercely with the pursued
prey.

On May 21st
1964, this breed was acknowledged by the Federación Cinológica Argentina and by the Argentinean Rural Society, which opened
their studbook to initiate registry.

It was not
until July 31st 1973 that the breed was accepted by the Fédération Cynologique Internationale as the first and only Argentinean
breed, thanks to the great passion, work and effort of Dr. Augustin Nores Martinez, its creator’s brother and successor.

GENERAL
APPEARANCE : Molossian normal type, mesomorphic and macrothalic, within the desirable proportions without gigantic dimensions.
Its aspect is harmonic and vigorous due to its powerful muscles which stand out under the consistent and elastic skin adhered
to the body through a not very lax subcutaneous tissue. It walks quietly but firmly, showing its intelligence and quick
responsiveness and revealing by means of his movement his permanent happy natural disposition. Of a kind and loving
nature, of a striking whiteness, its physical virtues turn it into a real athlete.

IMPORTANT
PROPORTIONS : As a mesomorphic animal, no part stands out from the whole body which is harmonic and balanced. Mesocephalic,
its muzzle should be as long as its skull.

The height
at the withers is equal to the height at the croup.

The depth
of the thorax equals 50% of the height at the withers.

The length
of the body exceeds the height at the withers by 10%.

BEHAVIOUR
AND TEMPERAMENT : It is cheerful, frank, humble, friendly, and not a hard barker, always conscious of its power. It
should never be aggressive, a trait that should be severely observed. Its domineering attitude makes it continuously
compete for territory with specimens of the same sex, most noticeable behaviour in males. As a hunter, it is smart,
silent, courageous and brave.

HEAD : Of
mesocephalic type, it looks strong and powerful, without abrupt angles or distinct chiselling. Its profile shows an
upper line which is concave - convex : convex at the skull because of the prominence of its masticatory muscles and its nape;
and slightly concave at the foreface. The head joins the neck forming a strong muscular arch.

CRANIAL
REGION :

Skull :
Compact, convex in the front to back and transverse direction. Its zygomatic arches are far apart from the skull, forming
a large temporal cavity which enables the large development of the temporal muscle. Its occipital bone is not very prominent
due to the strong muscles of the nape. The central depression of the skull is slightly noticeable.

Stop : Slightly
defined, as a transition from the convex skull region to the slightly concave foreface. From the side, it shows a definite
profile due to the prominence of the superciliary ridges.

FACIAL REGION
: As long as the skull.

Nose : Ample
nostrils. Black pigmentation. It is slightly elevated forwards, finishing off the concave profile of the muzzle.
From the side, the front line is perpendicular and straight, coinciding with the maxillary edge or slightly projected forward.

Muzzle :
Strong, a bit longer than deep, well developed in width, with sides slightly converging. The upper line is slightly
concave, an almost exclusive trait of the Argentinean Dogo.

Jaws/Teeth
: Jaws strong and well adapted; no under-or overshot mouth. The jaws should be slightly and homogeneously convergent.
They ensure maximum bite capacity. Teeth big, well developed, firmly implanted in line, looking clean without caries.
A complete dentition is recommended, priority being given to the homogeneous dental arches. Pincer bite, though scissor
bite is accepted.

Cheeks :
Large and relatively flat, free from folds, bulges or chiselling, covered by strong skin.

Eyes : Dark
or hazel coloured, protected by lids preferably with black pigmentation though the lack of pigmentation is not considered
a fault. Almond-shaped, set at medium height, the distance between them must be wide. As a whole, the expression
should be alert and lively, but at the same time remarkably firm, particularly in males.

Ears : High
and laterally inserted, set well apart due to the width of the skull. Functionally, they should be cropped and erect,
in triangular shape and with a length which does not exceed 50% of the front edge of the auricle of the natural ear.
Without being cropped, they are of mid-length, broad, thick, flat and rounded at the tip. Covered with smooth
hair which is a bit shorter than on the rest of the body; they may show small spots, not to be penalized. In natural
position they hang down covering the back of the cheeks. When the dog is alert they may be half-erect.

NECK : Of
medium length, strong and erect, well muscled, with a slightly convex upper line. Truncated cone-shaped, it joins the
head in a muscular arch which hides all bony prominences in this part, and fits to the thorax in a large base. It is
covered by a thick and elastic skin that freely slips over the subcutaneous tissue which is a bit laxer than on the rest of
the body. It has non-pendent smooth folds at the height of the throat, a fundamental trait for the function of the animal.
The coat in this part is slightly longer than on the rest of the body.

BODY : The
length of the body (from the point of the shoulder to the point of the buttock) exceeds the height at the withers by 10%.

Upper line
: Level; the withers and the pin bones of the croup are at the same height, constituting the highest points.

Withers
: Large and high.

Back : Large
and strong, with fully developed muscles forming a slight slope towards the loins.

Loins :
Strong and hidden by the developed lumbar muscles which form a median furrow along the spine. Slightly shorter than
the dorsal region, rising very slightly to the top of the croup. The development of muscles in the parts of the upper
line causes the dogs to show a slightly depressed profile without being actually so, which is enhanced in adults due to the
fully developed dorsal and spinal muscles.

Croup :
Of medium length, large and muscular; slightly showing the tips of both ilium and ischium. Its width is equal or a bit
less than that of the thorax; the angle to the horizontal is of about 30°, thus the upper line falling in a slightly convex
slope towards the insertion of the tail.

Chest :
Broad and deep. The tip of the breastbone is level with the tip of the shoulder joint (scapulo-humeral joint) and the
sternal line of the thorax is level with the elbow line. Large thorax providing maximum respiratory capacity, with long
and moderately curved ribs which join the breastbone at the height of the elbow line.

Abdomen
: Slightly tucked up beyond the bottom line of the thorax, but never greyhound-like. Strong with good muscular tension as
well as in the flanks and loins.

TAIL : Set
medium high, with 45° angle to the upper line. Sabre- shaped, thick and long, reaching to the hocks but not further
down. At rest it hangs down naturally; when the dog is in action, it is slightly raised over the upper line and
constantly moving sidewards. When trotting, it is carried level with the upper line or slightly above.

LIMBS

FOREQUARTERS
: As a whole, they form a sturdy and solid structure of bones and muscles, proportionate to the size of the animal.
Forelegs straight and vertical, seen from the front or in profile.

Shoulders
: High and proportioned. Very strong, with great muscular contours without exaggeration. Slanting of 45° to the
horizontal.

Upper arm
: Of medium length, proportionate to the whole. Strong and very muscular, with an 45° angle to the horizontal.

Elbows :
Sturdy, covered with a thicker and more elastic skin, without folds or wrinkles. Naturally situated against the chest
wall of which they seem to be part.

Forearm
: As long as the upper arm, perpendicular to the horizontal, straight with strong bone and muscles.

Pastern
joint : Broad and in line with the forearm, without bony prominences or skin folds.

Pastern
: Slightly flat, well boned, slanting of 70 to 75° to the horizontal plane.

HINDQUARTERS
: With medium angulation. As a whole, they are strong, sturdy and parallel, creating the image of the great power their
function requires. They ensure the proper impulsion and determine the dog’s characteristic gait.

Upper thigh
: Length proportionate to the whole. Strong and with fully developed and visible muscles. Coxo-femoral angle close
to 100 °.

Stifles
: Set in the same axis as the limb. Femoral-tibial angle close to 110 °.

Lower thigh
: Slightly shorter than the upper thigh, strong and with similarly developed muscles.

Hock joint
/ Hock : The tarsus-metatarsus section is short, strong and firm, ensuring powerful propelling of the hind limb. Sturdy
hock joint with a noticeable calcaneus (tip of hock). The angle at the hock joint is close to 140°. Sturdy hock,
almost cylindrical and at 90° angle to the horizontal. If present, dewclaws should be removed.

Hind feet
: Similar to forefeet, though slightly smaller and broader, but with the same characteristics.

GAIT / MOVEMENT
: Agile and firm; with noticeable modification when showing interest in something, changing into an erect attitude and responding
to reflexes quickly, typical for this breed. Calm walk, extended trot, with a good front suspension and a powerful rear
propelling. At gallop, the dog shows all of its energy displaying its power fully. The four feet leave simple,
parallel traces. Ambling (pacing) is not accepted and is considered a serious fault.

SKIN : Homogeneous,
slightly thick, but smooth and elastic. Adhering to the body through a semilax subcutaneous tissue which ensures free
movement without forming relevant folds, except for the neck area where the subcutaneous tissue is laxer. With as little
pigmentation as possible, through this increases with the years. An excessive pigmentation of the skin is not accepted.
Preference should be given to dogs with black pigmentation of the rims of labial and palpebral mucous membranes.

COAT

HAIR : Uniform,
short, plain and smooth to the touch, with an average length of 1,5 to 2 cm. Variable density and thickness according to different
climates. In tropical climates the coat is sparse and thin (letting the skin shine though and making pigmented regions
visible which is not a cause of penalty). In a cold climate it is thicker and denser and may present an undercoat.

COLOUR :
Completely white; only one black or dark coloured patch around the eye may be admitted, provided that it does not cover more
than 10% of the head. Between two dogs of equal conformation, the judge should always choose the whiter one.

SIZE :

Height at
the withers : Dogs : 62 to 68 cm. - Bitches : 60 to 65 cm.

FAULTS :
Any departure from the foregoing points should be considered a fault and the seriousness with which the fault should be regarded
should be in exact proportion to its degree.

N.B. : Male
animals should have two apparently normal testicles fully descended into the scrotum.

In 1928, Dr. Antonio Nores Martinez, a young Argentine physician, began to
develop a new breed of dog, which he called the Dogo Argentino. Using a methodical system, Dr. Martinez crossed a local breed,
known as the Old Fighting Dog of Cordoba, with a variety of breeds, including Mastiffs, Bulldogs and Bull Terriers. His new
breed demonstrated a talent for hunting big game, including wild boars and pumas, as well as strong guarding instincts. The
breed was recognized by the Federacion Cinologica Argentina in 1964, and by the FCI in July 1973.

Today, the Dogo Argentino is still used as a hunting dog, a guardian of property, a family companion, and an all-around
working dog.

The Dogo Argentino was recognized by the United Kennel Club on January
1, 2001.

GENERAL APPEARANCE

The Dogo Argentino is a large, white, short-coated dog with a smooth, muscular body,
displaying both power and athletic ability. The length of body is just slightly longer than tall, but bitches may be somewhat
longer in body than dogs. The length of the front leg (measured from point of elbow to the ground) is approximately equal
to one-half of the dog’s height at the withers. The head is powerful with a broad, slightly domed skull and a powerful
muzzle that is slightly higher at the nose than the stop, when viewed in profile. Ears may be cropped, or hang naturally,
close to the skull. The Dogo Argentino should be evaluated as a hunting dog, and exaggerations or faults should be penalized
in proportion to how much they interfere with the dog’s ability to work.

CHARACTERISTICS

The Dogo is an intelligent and courageous dog with a strong, natural instinct
to protect its home and family. Dogos are very social dogs and are happiest when included in all family activities. Dogos
make a strong distinction between familiar people and strangers, so it is imperative that they be well trained and socialized
at an early age.

Dogos are hunters of great courage and endurance, and will work individually
or in packs. They have also successfully been used in police protection work. An unsteady temperament is a serious fault.

HEAD

The head is large, but proportionate to the size of the body, and broad, giving
the impression of great power and strength, without abrupt angles or distinct chiseling. Viewed from the front, the head is
shaped like a square within a square. Viewed from above, the head is broad through the skull, narrowing slightly where muzzle
joins the skull, and then tapering only slightly to the blunt end of the muzzle. When viewed from the side, the length of
skull and muzzle are approximately equal, and they are joined by a distinct, but not abrupt, stop. The planes of the skull
and muzzle are not parallel. The skull is slightly domed and the bridge of the muzzle rises slightly from the stop to the
nose.

SKULL - The skull is broad and slightly domed, with a median furrow that diminishes
in depth and width from the stop to the occiput. Cheeks are well developed, relatively flat, and powerful. The supraorbital
arches over the eyes are moderately well defined. The occiput is not prominent.

MUZZLE
- The muzzle is powerful, slightly longer than deep, and narrowing very slightly from stop to nose. The bridge of the muzzle
slopes slightly upward from stop to nose. Lips are tight and moderately thick. Black pigmentation on the edge of the lips
is preferred.

Disqualification: Lips that hang
below the line of the lower jaw.

TEETH - The Dogo Argentino has a complete set of large,
evenly spaced, white teeth that meet in a scissors bite. An even bite is acceptable but not preferred. Large teeth and proper
occlusion are of extreme importance.

Serious Faults: Small,
weak or decayed teeth; incomplete dentition.

Disqualification: Overshot or undershot bite.

NOSE - Nose is large and black, with well-developed
nostrils. Some pink pigment on the nose is acceptable, provided the nose is predominantly black.

EYES - Eyes are of medium size, almond shaped, and set well apart and deep in their sockets. Eye color may
range from very dark brown to dark hazel, but darker eye color is strongly preferred. Eye rims are tight and preferably black
in color, although lack of pigmentation is not a fault. Expression is alive, intelligent and hard.

Serious Faults: Functional abnormality of eyelids or eyelashes.

Disqualifications: Eyes any color other than listed above; eyes not of
matching colors.

EARS - Ears are set on high on the outside edges of the topskull, and
may be cropped or natural. Cropped ears should be triangular in shape, short, and erect. Natural ears are drop, broad at the
base, short in length (reaching just to the corner of the lower jaw when hanging naturally) and tapering to a rounded tip.
Ear leather is thick. At rest, the ears should hang nearly flat and close to the cheeks, with little or no fold. The ears
may be semi-erect when the dog is alert. The outside of the ear is covered with smooth hair that is slightly shorter than
the body coat. Ear color may range from heavily spotted to solid black or brindle.

Disqualifications:
Unilateral or bilateral deafness.

NECK

The neck is of medium length and muscular, with a slight arch at the crest, and
tapering slightly from shoulders to the head. The skin on the throat is thick and elastic, and may form slight, smooth, non-pendent
folds.

FOREQUARTERS

The shoulder blades are long, wide, muscular, and well laid back. The upper
arm is roughly equal in length to the shoulder blade and joins it at an apparent right angle, lying flat against the chest
wall.

FORELEGS - The forelegs are well boned, strong and muscular. The elbows are set
close to the body. Viewed from the front, the forelegs are set moderately wide apart and perpendicular to the ground. The
pasterns are short, powerful, straight, and flexible. When viewed in profile, the bone of the pasterns is slightly flattened.

BODY

The chest is deep, well filled in and wide with ample room for heart and lungs.
The forechest does not extend much beyond the point of shoulder.The ribs extend well back and are well sprung from the spine, then flattening to form a deep body extending to
or below the elbows. The back is strong and firm. The backline falls off slightly behind the withers and blends smoothly into
the loin. The loin is short and broad with a muscular arch, and it blends smoothly into a gently sloping croup. The flank
is moderately tucked up and firm.

Serious Faults: Barrel
chest; flat ribs.

HINDQUARTERS

The hindquarters are broad, strong and muscular, normally angulated to balance
with the front assembly. HIND LEGS - Set well apart and parallel to one another when viewed from behind. Hocks are strong
and turn neither in nor out. Rear pasterns are short.

Serious Faults: Over-angulation; long hocks.

FEET

The feet are round and tight, with well arched toes. Pads are thick, black, and
rough in texture. Nails are short, strong and white. Rear feet are slightly smaller and broader than front feet. Dewclaws
may be removed.

TAIL

The tail is set on moderately high and is thick at the base, tapering to a
point. When the dog is relaxed, the tail is carried low and extends approximately to the hock. When the dog is moving, the
tail may be carried slightly above the backline, moving rhythmically from side to side. When the dog is excited, the tail
may be carried in a raised, upright position (challenge tail), but never curled over the back (gay tail).

Serious Fault: Gay tail.

COAT

Short and thick, with a glossy sheen. Hair is stiff, coarse and of uniform
length. A field conditioned coat or working scars should never be faulted.

Disqualification:
Long coat.

COLOR

White. Skin pigmentation that shows through the coat is not to be penalized
in mature dogs. One dark marking on the head is permitted provided that it does not cover more than 10% of the head. No other
markings are allowed with the exception of some light ticking, which is not to be confused with a solid patch. All other things
being equal, the whiter dog is preferred.

Disqualification: A solid patch of color anywhere except on the head as described, not to be confused with ticking.

HEIGHT AND WEIGHT

Height for mature males should range between 24˝ and 27 inches. Height for
mature females should range between 23˝ and 25˝ inches. A mature Dogo under the minimum height for its sex is disqualified.
Dogos are not a giant breed so a mature Dogo over the maximum heights should be severely penalized, because the additional
height detracts from its ability to work.

Dogos should always be presented in hard,
working condition. Weight should be sufficient so that the dog presents a harmonious blending of sturdiness and substance
with agility and athleticism.

The Dogo Argentino moves with power and agility, able to change gait quickly
and smoothly when in the field. When trotting, the gait is effortless, smooth, powerful, and well coordinated, showing good
reach in front and drive behind. When moving, the backline remains level with only a slight flexing to indicate suppleness.
Viewed from any position, legs turn neither in nor out, nor do feet cross or interfere with each other. As speed increases,
feet tend to converge toward a center line of balance. At a walk, the Dogo moves like a lion; with power, dignity and the
supreme confidence that he is king of all he surveys.

Poor movement should be penalized
to the degree to which it reduces the Dogo’s ability to perform the tasks it was bred to do.
